To all whom iri mag concern;

Be it known. that'l, GIDEON R. IBAGH, a citizen of the United States, residing at Allentown, in the county of Lehigh and State of Pennsylvania, have invented an Internal-Ccmbusticn Engine, of which. the following is a full and complete specification.

My invention relates more especially to that particular class of internal combustion engines used in motor vehicles, and. in which aplurality of cylinders are employed and the several pistons connected to a mark shaft CDIHHAOD. to all, the connections'heing such that the power is applied to the shaft from. the pistons successively. in the con str'ction of engines of this character it is customary to arrange the cylinders in parallel series or radially, and usually in pairs, the number being determined according to the size of the vehicle and power required to drive it.

In the present instance I dispose the eugine-cylinders radially, and have for the primary object 011. my invention to so construct and support a pair of cylinders as to form practically an engine section. whereby any number of such sections may be readily and conveniently coupled together to provide an engine with the required amount of YOWGI- it further object of my invention is-tc provide a multiple cylinder engine for mo"- tor vehicles which is simple and compact in construction, occupies a 'ininimuin of space, and is also effective in operation.

Other objects and advantages of, my invention will hereinafter appear, and What I claim as new, and desire to secure by letters-Patent, is more specifically set forth in the appended claims.

In the accompanying drawings, which form a part of this specification: Figure 1 is a front elevation of an internal. combustion engine constructed in accordance with my inventionand'including two pairs of cylinders or engine sections. Fig. 2 is a plan view, the engine being slightly turned with refercuceto Fig. 1. Fig. 3 is a vertical sectional View through one-of the engine sections. Fig. 4 a detail view of the connected Fig. 1s a detail sectional view on the line 5-4) of Fig. 1. Fig. 6 is a front elevation,-

partly in section, of the casting or frame of an engine section. Fig. 7 1s a vertical transverse sectional view thereoi'. Figs. 8 and 9 pistons of one of the engine sections.

are detail views of a plate which is attached to the front of the engine frame or casting;

like numerals of reference indicate like parts in all the figures of the drawings.

In carrying out my invention I provide an engine section or unit comprising a circular supporting-frame, a pair of radially r ispcsed engine-cylinders, operating connections for said cngine-cylinders, and a clan ..lia.i't to which the pistons are connected, all as hereinafter particularly described.

' The supporting frame of the engine-section is, in the present insance, made of a single casting and consists 6f an outer ring or rim 10, having inWardly-projecting reinforcing side flanges 10, 10 an inner ring ii, and vertical and horizontal webs 12 and 13,

respectively, connecting said rings, the inner ring being closed at one side by a Wall 14 nrvvhrch 1s formed one of the bearings, as 15,,for the crank-shaft 16 of the engine. Also formed integrally with this supporting-frame or casting are two cylindrical casings or jackets, 17 and 18, to receive the engine-cylinders, hereinafter described, said casings or jackets beingdisposed radially and on a line with each other. Viithin each cylindrical casing or jacket is mounted an engine-cylinder 19, secured in place in any suitable manner, for instance by ordinary screw-threads, as at 19*, and each cylinder is provided with a head 20, offset at one side to provide for the usual intake valve 21 and exhaust-valve 22, said valves being closed automatically by springs 23 and 2d, respcctivelygand the stem 25 of the exhaust-valve extended and provided with an anti'iriction roller 26 engaged by a cam 27 on a shaft :28, for mechanically open; ing said valve. In the present instance the intake valve 21 is opened to charge the cylinder by suction on the outstroke of the pis-' ton, but of. course said intake valve may be also opened mechanically in like manner as the exhaust-valve. The cam-shaft 28 is driven from the crank-shaft 16 by a suitable train of gearing (indicated in dotted lines in Fig. 1), and it will be noted that the aforesaid cam-shaft is mounted in bearings formed on the horizontal connecting webs 13 of the supporting-frame, and that 2?..CfiIIl-Sllflft is provided for the exhaust-Valve of each engine-cylinder. It "Will be noted, also, that the bearings 30, 30, for the idlevvhcels oi the two trains of gearing are on a face-plate Ell, which is attached to the front of the supportingdrameby screws 32, and. that the hearing, as 33, for the crankshaft is also formed on said face-"plate.

For the purpose oi maintaining either one or both of the exhaust-valves of the engineopen, to thereby permit the engine to run free without drawing in any gasole'ie or explosive-mixture, i provide aslide for each of said valves, said slide having a keyhole slot 35 (see Fig. 5) through the arger portion of which a collar 36 on the valvestem normally works. Now when the slide is shifted to the position shown in said Fig. tae smaller portion of the slot takes the stem 2-5 and the end of the collar abuts against the slide, thereby holding the exhaust-valve open against the action of its closing'spring. Each slide 3% is supported on boss 3"? on the engine irame, being connected thereto by a screw 38 passing through a slot 39 in said slide, the latter having an arm 3st by which it connected to a sliding-rod 40; it being understood that when two" engine sections are connected, as illustrated in Figs. 1 and 2, each operating rod 40 is of such length ns to operate two slides, and when three engine sections are coupled the rod is of a length to operate three slides, and so on. Likewise, when two or more engine-sections are coupled together the crank-shaft and valve-operating cam-shafts are (at proper lengths to correspond, and of course the cranks 45 011 the crank-shaft disposed so as to apply the power-to said shaft from the pistons in succession.

The cylin ers of each engine-section are disposed radially on a-line with each other, and the pistons, 41, 41, working in these cylinders are connected to operate in unison by a tubular member 42, the attachment of the pistons to said connecting member being made in the present instance by threading the reduced inner ends of said pistons into the enlarged outer ends of the tubular member, as shown in the drawings. The tubular connecting-member is provided with opposite slotsi l-i, forthe accommodation of the crank-shaft 1$, and the outer end of the crank 45, located within said tubular memher, work through slots 4a, thelatter being of such length as to accommodate the link or piston-rod 46. The piston-rod is connected to one at the pistons, or to one end of the tubular connecting member, by a pin 457: and, of course, inasmuch as the pistons are connected but a single link or piston-rod is required. The cranks and piston-rod con" nections may be of any app ved type, suitable means provided for supplying the bearings with oil. l urthermore, the heads of the cylinders, and valves therein are of the usual type, the head heir j provided with plugs or threaded caps 48, to give access to in order an engine of four cylmders two as throu h the connectin u l 7 b l3, as indicated in Fig. 3, and. in ti ,4 instance the closed walls 141:, it, of the two sec tions are brougit together and, l cs :31. applied to the orter sides oi ae eennected sections as shown in Fig. i lion thus connected the two pairs of euginecyliuders are disposed in the form of an X. (it course it a third pair of cylinders is d "ed third engine-section we be bolt-ed one side ofthe other two, t iceplate at that side being removed so that the additional section may be brought close against the adjoining one; and in this instance the cylinders of the added engine-section would be disposed on a line with the cylin rs of one of the other enginesections. Similarly a fourth engine-section could be coupled, and so on, and of course in each instance a crankshaft having the proper number and disposition of cranks, and cam-shaft having the proper number and disposition of cams, would be supplied, corresponding with the number of cylinders to the engine. By this arrangement, or thus constructing an engine-section, an engine having any number of cylinders may be readily and conveniently built up to suit requirements.

The operation of the engine is similar to that of the conventional type of internal rombustion engines, provision being made in.

the present instance to save the consumption of g'asolene or other hydrocarbon used for driving the engine by simply shitting the slides 3et so 'as to hold. the exhaust-valves open and allow the several engine-cylinders to draw in air through the exhaust pipes, Any suitable means may be provided for up era ting the rods 40 connected to said slides.
